AMD Ryzen 9 4900HS revealed to have 3.0 GHz base clock and 4.4 GHz boost clock; trails behind Ryzen 7 4800H in first 3DMark 11 tests

An AMD Ryzen 9 4900HS processor has been spotted being tested on the 3DMark 11 benchmark. The APU, which was recently leaked by a retailer listing for an Asus ROG Zephyrus G14 laptop, manages reasonably healthy physics scores ranging from 13,735 points to 14,590 points. However, this puts the Ryzen 9 4900HS behind its fellow Renoir chip, the Ryzen 7 4800H.

It appears both Tum Apisak and _rogame have been keeping a careful watch over the AMD Ryzen 9 4900HS and its subsequent performances on 3DMark 11. The mobile chip was revealed last month when it appeared as a component of an Asus ROG Zephyrus G14 laptop, and although neither Asus nor AMD confirmed its existence, it has now appeared on 3DMark 11 revealing some of its secrets. The 8-core chip can utilize 16 threads for processing performance and its clock rates go from 3.0 GHz to 4.4 GHz.

The AMD Ryzen 9 4900HS’s performance on 3DMark 11 seems strange on the surface. The Renoir APU managed Physics Scores (which are based on CPU load) that went from 13,735 points to 14,590 points. Although these scores put it ahead of fellow Ryzen 4000 chips like the Ryzen 7 4800U (12,490 points) and the Ryzen 7 4600H (12,690 points), the Ryzen 9 4900HS fell behind the Ryzen 7 4800H on 15,309 points. But there are some reasons for the higher-clocked part to not offer up better scores at the moment.

There is a discrepancy in the TDP for a start: The AMD Ryzen 9 4900HS is expected to have a TDP of 35 W whereas the Ryzen 7 4800H can be pushed a little harder thanks to its 45 W default TDP (although it can be set at 35-54 W by a laptop OEM). The data-miner _rogame shared a higher score for the Ryzen 9 4900HS while mentioning that the GeForce GTX 1660 Ti Max-Q GPU in the device was “working correctly this time” – so it seems the laptops involved with the initial benchmarks may have been slowing the APU’s potential performance down due to component issues and/or insufficient cooling solutions. Either way, better results can be expected in the future from the new Ryzen 9 4900HS processor, which will no doubt be another impressive addition to AMD’s growing Ryzen 4000 series.
